APPARATUSFOR WASHING AND DELIVERING COAL, 81.0.

SPECIFICATION forming part of Letters Patent No. 283,156, dated August 14, 1883.

Applicntioirfiled June .1, 1882. (No model.) Patented in England March 21,1876, No. 1,200, and in Canada June 10, 1882,

To al whom. it may concern Be it known that 1, CHARLES SHEPPARD, a subject of the Queen of Great Britain, resid- 'ing at Bridgend, in the county of Glamorgan,

Wales, have inventednew and useful Improvements in Apparatus for Washing and Delivering Goal, Ashes, and other Substances, (for which I have obtained a patent in Eiigland,

No. 1,200, dated March 21, 1876, sealed Sep 1o tember 9, 1876,) of which the following is a specification. i

The object of my present invention is to facilitate the washing and, purifying of the coal orother matter to be operated upon. The coal or other matter to be operated upon is, when necessary, reduced to suitable size by crushing. It is then fed, by elevators or other suitable feed means, into separate compartments, called bashes, or other suitable receivers, of which there may be one, two, three,orothernuniber. Each of these bashesor receivers is provided with a perforated copper floor near its upper part, on which the matters to be washed are received, and these floors incline toward the endopposite where the coal isfed in. These bashes or receivers are supplied with water to a level above that of the matters on the perforated copper floor, and this water is circulated by pump apparatus or other suitable means, producing an intermittent upward c irrent through the perforated copper floor and the matters resting thereon, whereby the shale, stone, or other i heavy particles sink to thebottom,-and the coal, coke, ashes, breeze, or lighter particles flow over with the water to the settling-chain her. The shale or other refuse separated from the coal, coke, ashes, or breeze passes into the rubbish-chamber 'by an opening. The extent of admission at this opening is capable of being regulated by adjustable sluices or valves, and the matters so received are carried forward in a trough or gutter at the bottom by-a revolving screw and then delivered at one end of it into a suitable receiver, and from thence elevated. The coal or other matter, ascleansed, flows with the currentof water from thebaslies or receivers into asettling-chamber, the bot tom of which is formed to receive a screw-con- 5o ductor, by which the settled matters are conducted forward to an elevator, by which they and delivered in a semi-dry state without the use of separate settling-ponds, and without the necessity for raising the water again to the machine, and without discharging foul water during the washing process.

That the invention may be more fully under:

stood, I will, by the aid of the accompanying drawings, proceed to describe means pursued by me in carrying the same into effect.

In the drawings, Figure 1 shows byside View, and Fig. 2 by plan view, parts of apparatus arranged according to my invention. Fig. 3.. represents separately a sectional view of some of the parts.

In each of the figures the same letters indicate corresponding parts.

a represents the elevator to raise the coal to be washed, and which may then, by means of a screw-conveyer, (shown in Fig. 2,) be delivered to the perforated floors b of three or other,

suitable number of compartments or bashes, b. The matters thus received onto thesefloors b are cleansed by the action of the pumps 0, one to each compartment, the action ofthe pistons of these pumps being to cause an upward current of the water through the perforated bottoms b on the under side of the matters supported by them. These floors also incline toward the end (1 which has openings at from each of the compartments-b, capable of adjustment by slides (P. The action of the water on the matters on the perforated floors b is to cause the separation of the lighter from the heavier portions, so that in the case of coal, coke, &c., while--shale or stone sinks to the bottom and thence passes into the rubbishchamber (1,130 be carried forward by the screw 70 therein, and then to be delivered as desired,

the coal, coke, breeze, or lighter particles float I00 over the upper edge, 22 of the chamber 1), by forated or formed of open-Work to allow of 20 which, according to my present improvements, it is conducted down to the lower part of the settling-chamber f, which is divided from the chambers I), under the respective perforated floors b,'by the partition 9; and this partition 9 is provided with passages of communication 9 through it, capable of regulation, so that the water may freely flow from one chamber to the other, and this water is maintained at aheight sufficient to cover the particles in their passage over the top of the edge 6. The matters,

as collected in this settling-chamber f, are conducted forward by a screw, h, or other suitable means, and are thence elevated by aseries of elevators, i, or by other suitable elevators, and, aided by chute i, delivered into wagons or other receivers. The matters raised are drained as raised by the buckets or lifters being perthe draining of the water therefrom and returning to the machine. I

Having thus described my invention, and means which I adoptin carrying the same into effect, I would have it understood that what I 25 claim, is

The described apparatus for washing and (lelivering coal and other substances, consistingof an elevator, a, compartments I), provided with inclined perforated floors b, and having 0 openings 61, the slides (1*, pumps 0, rubbishchamber (1, settling-chamber f, valves 9, 0011- ducting-screws, and the elevators t, substantially as set forth.

CHARLES SHEPPARD.
